IMO The source of energy is the momentum of the MH. This force is called the “driver” force. The resistive forces are called “resultant” forces. The resistive force of a flat tire is NOT proportional to the driver force. The “driver” force is far superior to the resistive force of a flat steer tire. Also, the resistive force vector of a flat steer tire is directly opposite and parallel to the bearing line of the driver force. It is not a lateral force. Even when the MH changes direction, the resistive force of this flat tire “pushes” straight back against the forward motion of the MH. And, it pushes back in a line that is parallel to the bearing line of the MH. HOWEVER, if the steering wheel becomes unattended at the time of the blowout, the push back of the flat tire is of sufficient force to turn /steer its spindle, and this turns the spindle of the other steer tire, which has much more traction than the flat tire. THAT’S when the MH changes direction. But, if the steering wheel is properly attended without interruption, the MH will NOT change direction. The Michelin video and the Tuscany video are of these two scenarios. IMO it makes more sense to believe this, otherwise you will always feel insecure when driving your motorhome. I know I would never drive any vehicle if I did not believe this. To me, a blowout is just an expensive inconvenience. That’s the reason I cruise at 65 mph instead of 75 mph. IMO one of the do-not-forget items on your checklist should be that a blowout can happen when you least expect it. But, the majority of them happen in the summertime when driving fast on a hot road surface.
P.S.
I can keep on steering just fine WITHOUT depressing the accelerator. The power steering is all the help I need. The momentum keeps me going as fast as I need, even if the speed is dissipating.
